CAUTION!
Risk of damage to the pH sensor!
The glass membrane of the pH sensor can be
damaged due to drying out. The water vapour gen-
erated by sterilisation is sufficient for moistening it.
Therefore:
– Never sterilise a completely empty and dry ves-
sel.
Fill the vessel with a little water, approx. 10 mL per litre of
working volume to generate sufficient steam in the vessel dur-
ing sterilisation. Add basal salts if needed.
Sterilise the vessel.
Add the culture medium and inoculum under sterile conditions.
All heat-labile components are usually sterile filtrated and
added by injection or with the inoculum afterwards.
NOTICE!
This method is often used for cell cultures.
